Read MoreThe Dunkermotoren PLG 52 HT Series Planetary Gearbox is an industrial-grade, high-torque solution engineered for demanding motion control applications. With a steel ring gear and precision straight-toothed stages, it offers exceptional durability, high torque transmission, and long service life—making it ideal for use in factory automation, medical devices, robotics, and mobile machinery.
This series supports reduction ratios from 3.33:1 to 512:1 across 1-, 2-, and 3-stage configurations, delivering continuous torque from 1.5 Nm up to 26 Nm depending on the version. With high acceleration torque ratings (up to 35 Nm) and emergency stop torque up to 48 Nm, the PLG 52 HT is well-suited for both steady-state and dynamic operation modes (S1 and S8). It achieves up to 90% efficiency in single-stage designs and maintains high performance across all stages.
Engineered with double ball bearing support and capable of handling axial loads up to 500 N and radial loads up to 350 N, the PLG 52 HT delivers reliable operation under significant mechanical stress. Lifetime lubrication, IP65 protection, and optional configurations such as food-grade and low-temperature lubrication make this gearbox highly versatile and virtually maintenance-free.
For high-performance, compact, and rugged power transmission, the PLG 52 HT Series delivers unmatched value in demanding industrial environments.
